YN22051 Cable Flexing (three) testing machine 
 Overview: 
 Two three Flexing instrument the two HA (ie, wire and cable for Standardization Technical Committee and the National Standardization Technical Committee) based on the current needs of the international market. The addition of the GB/T5013.8-2008/IEC60245.8: 1998 Rated voltage 450/750V rubber insulated cables Part 8; Cords for the new combined testing instruments, its performance structure that meets the original GB / T5013.1-2008, GB/T5013.8-2008, GB/T5023.2-2008 standards, but also to meet GB/5013.8-2008 new standards. The instrument design novel structure, reliable performance, convenient operation, one machine. The high accuracy of the test data, is the ideal test instrument on the market today. It applies to the following determination of the rated voltage of 450/750V, two cores or more than two core PVC insulated cables, rubber insulated and Cords for mechanical strength. Does not apply to the nominal cross-sectional area greater than 4mm2 flexible cables and concentric glue than 2 layers, glued core is greater than 18 core cable. 
 Main technical parameters: 
 1, test specimen type: two-core single-phase, three-phase three-wire, three-phase four-wire 
 2, the test method: No-load, single-phase (two core), three-phase (three phase three wire / three-phase four-wire) can be any select 
 3, the test results to determine the way: A light indicates: O, R, S, T phase wire and automatic shutdown 
 B, light indicates: R / S, R / T, S / T, the R / O, the S / O, the T / O short circuit and automatically shut down 
 C, light indicates: O, R, S, T and pulley short circuit and automatically shut down 
 Flexing speed: two pulleys is 0.33 m / s, three pulley is 0.1m / s 
 Flexing the trip: ≥ 1M 
 3, the test current: 0 ~ 35A 
 4, the test voltage: two-wire single-phase AC: 0 ~ 250V (adjustable) / Three-core three-phase AC: 0 ~~ 450V (adjustable) 50HZ 
 Hammer: the two pulleys 0.5,1.0,2.0,3.0,4.0 kg each two, three pulleys for 21N, 28N, 42N of each two 
 6, the pulley structure: car for the second and third pulleys share structure, easy to replace 
 7, the two pulley: The pulley diameter: 60,80,120,160,200 mm, flat and concave bottom pulley a 
 Three pulley: the pulley diameter, respectively, 40,45,50 mm a
